Because were twins, they were subjected to numerous experiments, often times injected with unknown diseases to see how they’d react.

“The most dangerous of the experiments were being injected with germs, diseases and drugs,” Mozes Kor wrote.

“ I was injected with one of those diseases and I was supposed to die. I beat the odds and I survived. But I know that from the 1500 sets of twins, only 200 individuals survived. The blood drawing was painful, but not as dangerous.”

Mozes Kor explained they also had to stand or sit naked for up to eight hours while they were examined.

“It was so demeaning that even in Auschwitz I couldn't cope with it. The only way I could cope was by blocking it out of my mind, so I have very few memories of those long hours.”

Despite the horrific treatment they received, Mozes Kor said she not only went on to accept what the Nazis had done to her and her family, but also forgave them for their unthinkable acts.

It started in 1993, she wrote, with Hans Munch, a Nazi doctor who later testified to the existence of the gas chambers.

“I decided to forgive him, in my name alone,” she wrote. “Then I decided to forgive all the Nazis for what they did to me. It didn't mean I would forget the past, or that I was condoning what they did. It meant that I was finally free from the baggage of victimhood. I encourage all victims of trauma and violence to consider the idea of forgiveness - not because the perpetrators deserve it, but because the victims deserve it.”

Mozes Kor, who returns to Auschwitz annually, says going there for the first time after 40 years left her with a feeling of triumph.

“It was like returning to a place that for 40 years I wondered at times if it was real or was it a figment of my imagination? And to realize it was real, that what I remembered was correct, and that I actually recognized many of the buildings, removed that big monstrosity from my imagination."

"And also the fact that I could go into the camp and walk out and nobody shot at me, that feeling of being free was very, very reassuring. I realized that I have beaten the Nazis. I survived in spite of what they did to me,” Mozes Kor wrote.
